Definitions

  • the present invention relates to a vehicle having a transmission assembly for transmitting a torque generated by a prime mover to a drive axle of a vehicle, having a power shift transmission and a drive clutch. Furthermore, the present invention relates to a vehicle with a transmission assembly and a method for operating a transmission assembly.
  • Gear arrangements of the type mentioned are known from the prior art, in particular in agricultural utility vehicles, for example in tractors.
  • a noticeable shift shock occurs because the multi-shift clutches shifting the different gear ratios of the power shift transmission are hydraulically opened or closed unmodulated. This leads to significant torque fluctuations in the drive train of the vehicle, which is perceived by a driver of the vehicle as jerky and uncomfortable and therefore reduces the ride comfort.
  • a suppression of the shift jerk could be achieved, for example, by a corresponding control of the drive unit, so that a kind of synchronization of the output speed of the drive unit takes place with the new load gear shift stage.
  • this control of the drive unit could be complicated to implement, since the generally complex control of a drive unit would then be extended by a further functionality. Such a control can also result in increased fuel consumption of a drive unit designed in the form of an internal combustion engine.
  • a transmission assembly for vehicles which has a power shift transmission, at least one multi-plate clutch and another power shift transmission for shifting for larger speed ranges.
  • a button is manually operated by the driver, whereby the multi-plate clutch provided there is opened for a predeterminable period. In that regard, this is intended to reduce or avoid the resulting shift of the power shift shift shock.
  • the object underlying the invention is seen to provide a vehicle with a gear assembly of the type mentioned, by which the aforementioned problems are overcome.
  • the pressure caused by the switching operation of the power shift transmission should at least be largely compensated and thereby a standstill of the vehicle can be avoided.

  • the vehicle according to the invention is in particular an agricultural or industrial utility vehicle, for example a tractor or a construction equipment.

  • the power shift transmission can be switched under load in all switching stages, without interrupting the transmission of torque from the drive unit to the drive axle.

  • the drive clutch with a predetermined characteristic and / or characteristic can be controlled in a switching operation of the powershift transmission.
  • a characteristic in the form of a look-up table could be stored in a control device assigned to the drive clutch, for example, the hydraulic pressure values of a hydraulically actuable clutch Function of the time contains, from which the switching operation is initiated. Between the individual values, a linear hydraulic pressure curve could be controlled. Since the timing of the clutch operation is different between upshift and downshift, two lookup tables are preferably provided.
  • the clutch can be controlled with a characteristic and / or characteristic curve in a switching operation of the powershift transmission, which takes place in dependence on the currently present operating state of the vehicle and / or the drive unit.
  • a characteristic and / or characteristic curve in a switching operation of the powershift transmission, which takes place in dependence on the currently present operating state of the vehicle and / or the drive unit.
  • different driving conditions can be addressed individually in an advantageous manner, wherein the vehicle is versatile with consistent ride comfort.
